Application filed August 16, 19112.vr Serial No. 715,429.

To all whom it may concern I Be It known that l, CHARLES J. GRIFFITH, acitizen of the United States, residing at fSt. Louis, Missouri, haveinvented a certain new and useful improvement in Railway- Crossings, ofwhich the following is a full, clear, and exact description, such aswill enable others Skilled in the art to which lit pertains to make anduse the same, reference being had to the accompanying drawings, formingpart oit' this speciiication, in which Figure l' is a plan View of apair of inte-` gral crossing rails constructed in accordance with myinvention. Fig. 2 is an elevational view partly in section taken on theline 2 2 of Fig. 1. Fig. 3 is an enlarged cross sectional view taken onthe line 3 3 of Fig. 2. Fig. 4i is an enlarged sectional view taken onthe line 1 1 of Fig. l. Fig. 5 is an enlarged cross Sectional view takenon the line 5 5 of Fig. 1. Fig. 6 is a plan view of a crossing frogconstructed in accordance with my invention. Fig. 7 is a plan view of aturnout rail Section constructed in accordance with my invention. Fig. 8is an enlarged cross sectional view taken on the lines 8 8 of Figs. 1and 6.

My invention relates to new and useful improvements in railway crossingsof thLx type shown in my Patent No. 1,049,575, issued January 7, 1913,the principal object of my present invention being to construct arailway crossing wherein the crossing rails are formed integral witheach other in order toprovide a very strong, rigid, and sub- Stantialstructure, and the rail members of which crossing are of hollowtriangular shape in cross section, thus providing a wide base that willreadily resist all side Strains and stresses, and the material formingthe body portions of the rails being so disposed as to obtain thegreatest possible strength with a minimum amount of material.

By my improved construction a crossing can be produced at less cost thana crossing of ordinary construction owing to the reduced amount ofmaterial used together with the absence of bolts, rivets, and likefastening devices, and my improved crossing has greater strength andrigidity than an ordinary type of crossing owing to the peculiarconstruction of the rails and the disposition of the metal therein.

A further object of my invention is to provide simple means on the endsof the integral crossing rails wherein ordinary railway rails may bereadily attached to the crossing rails. v

To the above purposes my invention consists in certain novel features ofconstruc-L tion hereinafter more fully described and claimed.

, Referring by numerals to the accompanying drawings, A `designates thecrossing rails, the same being formed integral with each other and eachrail comprises a base plate 1, a pair of upwardly extending inclinedwebs 2, the upper' ends of which are united and formed integral withsaid upper ends is a ball 3. n

Formed yintegral with the side of each ball 3 is an upwardly curvedlongitudinally extending flange-guard 4, rand the space 5 between thisguard and the ball of the rail forms the flange track traversed by theflanges of the car wheels.

The base plate 1 and the webs 2 'are compa-ratively thin and vbyxreasonoftheir triangular arrangement a very strong and subf stantial hollowbase is formed for the crossing rails which arrangement readilywithstands. side stresses and vibration.

Formed integral with the ends of the crossing rails are base plateextensions 1a and web extensions 2a and these extending portions serveas points of attachment for ordinary lrailway track rails B, and inorder that said ordinary rails can be positioned between the webportions 2a the sides ofthe base flanges of the ordinary track rails arecut away as shown in Fig. Sink order that the parts can bereadilyassembled.

The ordinary rails are fixed to the exteny sions 2a by means of bolts orrivets 6. Where hollow triangular rails are used as track railsextensions 7 are formed on their ends and these extensions enter thehollow end portions of the crossing rails and are attached thereto bymeans of bolts or rivets 8 (see Fig.

In Fig. 6 I have shown a frog crossing constructed in accordance with myinvention and in Fig. 7 is shown a turnout rail.

My improved construction enables me to form a railway crossing havinggreat strength and rigidity and a crossing thatk will materially reducepounding and jarring resulting from the vibration due to the passage ofcar wheels over the crossing. vBy forming the crossing rails integralall nuts, bolts, and like fastening devices which are ordinarily used infastening crossing rails to each other are dispensed with.

It will be readily'understood that minor changes in the size, form andconstruction of the various parts of my improved device may besubstituted for those herein shown and described without departing fromthe spirit of my invention, the scope of which is set forth in theappended claims.

I claim:

l. The herein described railway crossing comprising crossing railsformed integral with each other, each of which crossing rails comprisesa base plate, a pair of inclined webs integral with the base plate and aball integral with the upper ends of said webs the base plateand webs ofeach crossing rail being extended at the ends thereof to receive andserve as points of attachment for track rails.

2. The hereindescribed railway crossing comprising crossing rails formedintegral with each other, each of which crossing rails comprises a baseplate, a pair of inclined webs integral with the base plate, a ball integral with the upper ends of said webs, and a flange-guard integralwith said ball the base plate and webs of each crossing rail beingextended at the ends thereof toreceive and serve as points of attachmentfor track rails.

3. A railway crossing comprising integral crossing rails that are hollowand of triangular shape in cross section, and hollow triangularextensions on the ends of said rails adapted to receive the ends ofadjacent track rails;

4. rlphe hereindescribed railway crossing comprising crossing rails thatare formed integral with each other, each of said rails comprising abase plate, a pair of inclined webs, a ball on top of said webs, andhollow triangular extensions at the ends of the crossing rails, whichextensions are adapted to receive the end portions of adj acent trackrails. Y

5. A railway crossing composed of intersecting crossing rails, thebodies of which are hollow and of triangular shape in cross section,balls integral with the tops of said hollow body portions and hollowtriangular extensions at the ends of said rails, which extensions' areadapted to receive the end portions of adjacent track rails.

6. A railway crossing comprising hollow intersecting rails, the openingsthrough which rails are triangular in cross section, and hollowtriangular extensions of the ends of said rails for the attachment ofthe ends of adjacent track rails.

In testimony whereof I hereunto aiiix my signature in the presence oftwo witnesses, this 14th day of August, 1912.
